摘要
Bluetooth（蓝牙）技术是一种适合短距离通信的无线传输技术，一般传输距离为几十米。Bluetooth技术为办公室或家庭内设备连接提供了无线解决方案。与红外接口不同，Bluetooth通信不需要设备之间的对准，也能在一定程度上克服障碍物的阻挡，具有很大的优势，因此受到人们的高度重视。
本课题基于Bluetooth技术实现PC与PPC（Pocket PC）之间的通信，建立一个基本的通信框架，以实现即时的数据通信，并在此基础上开发一个简单的家电控制模拟系统作为通信验证。本文先从为了解决有线连接带来的麻烦引入蓝牙技术，接着介绍了蓝牙的协议层次和几个核心的协议，重点介绍了RFCOMM协议，之后对几种短距离无线通信技术进行了比较。最后介绍了本设计的实现方法，并且测试成功。

Abstract
Decided as a short-range wireless networking protocol, the distance that the Bluetooth technology can transmit is as far as dozens of meters. Bluetooth technology can normally provide cable-replacement technology to connect devices at home or in work place. Unlike IrDA interface, Bluetooth can overcome the obstacle without devices straight. To this extend, it has dominant superiority.
My project is on the basis of the technology of Bluetooth that supplied a connection between PPC and PC. Iinstant data and files can be transferred by building a transfer frame. Then, simulate simple system comprised of home electrical appliance. Firstly, this paper introduce Bluetooth technology and Bluetooth core protocol ,then emphasize RFCOMM protocol .Secondly, it introduce the way of carrying out the communication between PPC and PC. At last, the way is testified to succeed.
